Kuo for me. When all is equal he's the better pitcher hands down. Once League is relegated to setting up for Aardsma he's just another setup man that is no better or worse than anyone you'll be able to find in FA. Not to mention that Kuo, when/if healthy, should be the heir to Broxton's 9th inning duties.

Hal·la·day, n. 1. every fifth day in Philadelphia. 2. a day of rest for the bullpen. 3. innings eater. 4. doc. 5. ace.
